GUIDE-WHEEEFOR PLW-MOTOBS.

Patented Apr. 12, 1910.

To -all whom 'it may concern:

Be it known that we, EDWIN M. WHEE- LooK, residing at Minneapolis, in the county of Hennepin and State of Minnesota; EM- ERY F. WHEELocK, residin at Northfield, in the county of Rice and tate of Minnesota, and DIGKINBON O. WHEELOCK, resid-V is to provide means for guiding the motor' to cause it to travel' at a proper distance from and along' the side of a previously formed furrow. This object we accomplish by providing an independent guide wheel adjustably supported in front of the .motor and adaptedto A'Contact with theeunplowed ,side of 1a furrow and therehyfguide" the motor.

Our improvement is illustrated che accompanying drawings, in which- Figure 1 is a planview and Fig. 2 aside elevationofan engine or motor embodying our improvement,- -showing the guide wheel in operativev osition; Fig. 3 1s a v iew si-milarto Fig. 2 ut showing the guide wheel in elevated or inoperative po-v sition; 4:- to 8, inclusive, are detached views of part-s of the devices for raising and lowering the guide wheel.; and Figs. 9 and .10 aredetail views of parts ofthe devices for s wiveling and adjusting. the guide wheel su port.

.e have-'selected for the purpose of illustration, and havegshown inthe drawings in somewhat diagrammatic form, an ex losiveengine motor, which isgthe type o motor we ,prefer to use for' plowing, but our improveniente are adapted-tobejused in connection with motors of --other types.

In ,the drawings inegi-@negarle mais; fra/meot -the motor, Zthieplatfonn for the operator, 3l the. explojsirefen in e, i the drivwheels, the dividedfjront, axle,- which` is relfeifahvlyv suspended -fromzthe frame l by gangr- @ts Sandstayed by' braces-9", k6 the-angular arms pivoted to the agile-.7 and-.litho equalizer 'for .the pivot'y dfmenffiiersof .the

ends of a cable or chain 12 which runs around. a .pulley 13 on the end of an operating rod 14. which is journaled in a hanger 15 and extends rearward and has a handwheel 16 in convenient position for an operator on the platform 2 to turn it for steering the motor. All of these parts may be of any usual or suitable construction. A gang of plows (not shown) may be connected t0 the motor frame in the customary way by the chains 17, or rods, or other suitable means, to enable the motor to draw' the gang for-plowing.

To relieve the operator of the strain and labor of giving constant attention to the steering devices while plowing in order that the motor and plows may move in proper direction with relation vto the previously plowed ground, we provide a guide wheel 18 arranged a short distance in front of the machine.- The inner side of this wheel is beveled, as shown at 19, adapting it to bear against the land-side 20 of the furrow 21 to prevent the motor fromv moving away from the furrow; and ,the operator can, bysetting the steeringgear 'in position to give the motor agslight tendency to move in vthat direction, obv'iate any tendency of the motor to move in the opposite directIon, or toward .the plowed ground. Such guide Wheel is the side 'oit-Qa: previously formed furrow. It is preferable to provide the guide. wheel with`a relatively wide tread as shown, and

lto permit it in use to roll on the bottom of the furrow, but, obviously, the tread may if desiredbe made narrow, so that the wheel Vwill be little more than' af .r. d isk, and, inl that mon. ted-in a 22 the lower of: a :spindle .Y

tiGn- 260i?- ialdle of ener-of the steer- 'mg 'wheels 16.-. Tliet lower end ofthe ]ournal v box abatsthe bodvpt fina propenpositowon the spindle."

l -Which engages the On the upper portion of the spindle is a crown wheel 29, which may be fastened by a set-screw 30; and a bevel pinion 31 is arranged in mesh with the wheel 29, and is carried on the end of a tubular body or pinionrBl and therewith' the crown-wheel 29 and spindle 23 to vary and adjust the inclination of the guide wheel.

For turningthe pipe 32 the bore38 of its rearward portion is made square or angular andcwithin it is arranged a correspondingly angular rod 39 adapted to slide therein,

'wherebyrthe members 32 and 39 constitute a telescoping shaft for o rating the pinion 3l.' To enable the shaft member 39 to be operative when the guide wheel carrier is moved vertically or laterally, its rear end is connected by 'a suitable universal joint 40 withthe end of an operating rod 4l which y 1s mounted in suitable journal boxes 42 andl V tn'and extends to the platform 2, a handwheeiftebeing'providedon its end, so that of the steering wheels.

thfzoperator, by turning the handwheel,

can, adjust the direction of travel of theV guide wheel as desired, whatever may be .the course of 'travel of the'steeringwheels 6, for the teleseoping shaft for operating the pinionl 4will compensate for the' variations of distance between the spindle 23 and joint 40 caused by changing the courses For raising and lowerin the guide wheel its carrier 25, which is journaled on the wheel airis and stayed Vby a bracefi pivoted to .the e axis, is adjustably mounted on a ort46, which preferably consiste of a pieceof gas-pi e. To enable the carrier 25 to adjust itseltalong its' support as required when the direction of travel of thesteering wheels is chaned, anti-friction rollers l.t'supported from t 'af'.pair of hangers 48 engage the upper and vided on the-su port to eA carrier bar by lower.- surfaces of the support 46 and allow the carrier to Ninove freely thereon in lateral direction between the stops-49 and 50 prorevent movement o enable the supheyond proper imits.

"port 46 to be operated for raisingandlowerin the guide wheel it is connected an eye' 1 on its inner end with an e e-bo t 52 secured;I to the front of the fixed axle 7; and a' cable 53 fastened to the support near its middle is made to run on a pulley 54 inolnjitedI on a standard 55 at the front of -a previously made 'tiallyas set forth. r

side of the main frame. A sprocket-wheel 58 on the shaft 57 is connected by a; chain Y 59 with asprocketwheel loose on the shaft 61 of the motor driv' mechanism but provided with a friction sk 62 on its side adapted to be enga ed b clutch member 63 splinedg on t e shaft 61; and a clutch-shifter 64, pivoted at 65 to a cross-bar 66, enables'. the operator at will to start and stop the Acable wind mechanism to raise and lower the guideuwxeel devices. To hold the latter in their adjusted positions a ratchet 67 provided 4on the sliaft is engaged by a dog 68 .pivoted at 69 toV the frame'and havin an arm 70 which is connected to a sliding rod 71 by 'means of .which the operator can move lthe dog to and from lockingl engagement with the ratchet. By means of these devices the o erator is enabled to utilize the power of t e engine to lift the guide wheel from the ground,

and the locking devices will hold it in elevation the locking dog is again freed by the oteraltor, when the-wheel will. gravitate e und. i

In peration, while plowing at the side of furrow, the guide wheel runs on the bottom 'of the furrow with its beveled side vadapted to properly contact -with,the land-side whenever the course of the motor is such as to-ause such contact, 'and the operator is able, by turnin the rod 41, to vadjust the inclination 'of t e guide wheel relative to the direction of the motor movement as 4may be required. At the end of a furrow he may, as he Wishes, either lift the guide wheel from the ground, or, when theV conditions permit, allow it to remain on the'grcund and be free to adjust itself to the course of movement taken by the motor.
